When an action is so incredibly hard it reaches beyond the definitions of tough and or difficult alone.
This equation is so toughicult. I think I might lose it.

when something is tough and difficult
This is a toughicult decision!

A combination of tough and difficult. Used when you are so tired that all words just blend together.
The day after pulling an all nighter is extremely toughicult.
